If you are talking about this one: http://www.newegg.com/Product/Produc...82E16820211245 I would be a little hesitant to buy that because it does not clearly state it's class speed in the specifications or item title. The only confirmation (that isn't definte) is the picture of the case which says Class 6. I emailed newegg customer service, and they couldn't even confirm the class speed.
